I really like the sound of the whole Vintage Compressor series from Native Instruments. I don't know if the VC 76 actually sound identical to a real Urei 1176 but I don't really care as it's the result/sound that counts which is really good, flexible, fast to operate and warmish.
They're actually modeled by Softube and the VC 76 sounds extremely similar to the Softube FET; both have a useful sidechain input and both can do parallel compression. The Softube FET has a few more advanced features which I didn't feel like they justified the price.
For those interested: the FET has a more advanced sidechain (but you could achieve the same by adding an EQ), a lookahead function for even faster attacks and a nice saturation when driven hard (but when adding the free Softube Saturation plugin in front of the VC 76 it sounded very similar again).
I actually preferred the looks of the VC 76 and bought the whole Vintage Compressor bundle for less than half of the price of the FET as they all have a similar "sound" to it which I quite like.
